Answer:
x ≈ 3.7 m
Step-by-step explanation:
Use the right triangle on the left to find the height h , using the sine ratio
sin39° = 
= 
( multiply both sides by 7 )
7 × sin39° = h , then
h = 4.4
Using the tangent ration on the right side right triangle, then
tan50° = 
= 
= 
( multiply both sides by x )
x × tan50° = 4.4 ( divide both sides by tan50° )
x = 
≈ 3.7 m ( to 1 dec. place )

Answer:
Step-by-step explanation:
csc(Ф) is equivalent to the inverse of sin(Ф)
Since sin(Ф) = 3/7, the inverse of this would be 7/3
So, 
Step-by-step explanation:

Acceleration is simplified by assuming it is the constant -g
a=-g we integrate this with respect to time to get v...
v=-gt+C where C is the initial velocity in this case 14ft/s so
v=-gt+14 integrate again to get the height function
h=(-gt^2)/2 +14t +C we are not given an initial height so C is 0
h(t)=14t-gt^2/2 letting g=32 and neatening up a bit...
h(t)=14t-16t^2
